ters, as the type specimen has dried somewhat out of shape from having 

 been jilaced in too strong alcohol. The figures accomj)anj'iug the orig- 

 inal description are extremely poor, that representing the top of the 

 head (fig. 2 a) being particularly inaccurate, inasmuch as the rostral and 

 superciliary are drawn nearly twice their comparative size. 



On the whole, the status of the new species is about the same as that 

 of Ch. hottw. They should be recognized until conclusively proven to 

 be ouly individual variations of the same species. 



With this proviso, therefore, we distinguish at present three species, 

 as follows: 



a' 39 scale rows Charina bottce. 



a^ 43 scale rows, or more. 



&' Posterior nasal uot in contact with anteorbital; prefrontal not entering 

 orbit Charina plumbea. 



b- Posterior nasal in contact with anteorbital; prefrontal entering orbit. 



Charina irachyopa. 



The synonymy of the genus and the supposed three species would 



stand thus : 



Charina Gray.
